BIOLOGICAL CONTROL in vitro of Colletotrichum sp. ISOLATED FROM ROÑA SYNDROME IN AVOCADO Persea americana Mill. IN MICHOACAN
Bibliographic record
Abstract
Phytosanitary reviews in different avocado orchards in agroecological zones of Michoacn reveal diversity of symptoms attributed to Colletotrichum spp. The objective of this research was to isolate the pathogens associated with avocado scab syndrome, verify their pathogenesis, as well as carry out an in vitro biological control. Samples of avocado fruits with scab syndrome were collected in the municipalities ofSan Juan Nuevo, Los Reyes and Uruapan. The pathogen was isolated, pathogenicity tests were performed, and in vitro biological control was carried out based on four treatments:Baktillis (Bacillus subtilis) 1 mL/L, Natucontrol (Trichoderma harzianum), 0.3 g/L, Labrador (toxins of T. harzianum) 0.024 g/L and Bactiva (Bacillus spp.) 0.16 g/L, and an absolute Witness, with a completely random design. It was determined the presence of Colletotrichum gloeosporioides., based on morphological attributes. Corchosis symptoms were produced in the inoculated fruits, which were not similar to the symptoms presented by the fruits from which the pathogen was isolated. In which, the Colletotrichum gloeosporioides, it can also cause scab syndrome, but it is not responsible for the typical scab or purple spot on avocado. The product that had greater control was Natucontrol (T. harzianum).

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
